Among the protein powder pros and cons, one thing is sure–protein is an essential nutrient no matter what eating plan you follow. When it comes to weight loss, consuming more protein in your diet helps you reduce hunger and increase fullness. With numerous options on the market, it can be overwhelming to figure out which, if any, protein powder to purchase. Consider these pros and cons to find the best product to meet your dietary needs and help you reach your weight-loss goals.

Protein powder pros and cons

Protein powder pros and cons depend on what type of plan you are following

Are you following a plant-based diet? Is your focus on making sure every calorie counts? Clearly, protein powders conveniently help you get more protein in your diet, but how do you choose? Let's look at the most common types based on the source of the protein.

Whey-based

If you don't have any dietary restrictions, you have a variety of protein powders from which to choose. A milk-based, high-quality protein, whey protein powder is often the most affordable. It is noteworthy from a nutrition standpoint because of its high biological value, meaning it is very usable by the body. It also contains high amounts of leucine, an essential amino acid that triggers muscle protein synthesis. Look for a powder with little to no added sugar to reduce calories. Many manufacturers have moved beyond the traditional vanilla and chocolate flavors with more exciting choices for your palate, such as pumpkin spice, berry, and peanut butter.

Soy-free

You have a fairly plentiful collection of protein supplement powders to enjoy when following a soy-free diet plan. Keep watch for powders that contain whey, egg white, seeds (pumpkin or hemp, for example), peas, collagen, or casein as their base. If you are trying to lose weight, soy-free protein powders can fit your plan as long as the calories stay in check. Read the nutrition facts panel to find the lowest-calorie, highest-protein option.

Dairy-free

While weighing the protein powder pros and cons, you may prefer or require dairy-free. If so, steer towards powders labeled as vegan. If you avoid dairy because of lactose intolerance, there are several lactose-free, but dairy-based, powders available. They are derived from milk protein, and yet the lactose or milk sugar is removed during processing. Depending on processing, powders derived from soy, peas, collagen, egg white, seeds, or a mix of dairy-free proteins are safe for those with dairy allergies.

Vegan

If you follow a plant-forward diet, you're in luck! You can find single-ingredient powders such as pumpkin seed or hemp seed powder or blended products such as pea protein mixed with seed and grain proteins. Read the ingredient list carefully, as some powders may contain plant-based proteins as well as sweeteners like honey.

Collagen

A protein that binds tissues in fish and animals, collagen is a popular supplement. One ounce of collagen protein powder contains 25g of protein. In addition to providing protein, a collagen-based powder may benefit bone, joint, and skin health.

Allergy alert

If you have a food allergy, read the fine print before buying a protein powder. Although a product may be marketed as plant-based and contain vegan-only ingredients, it may be manufactured in a plant that processes egg, milk, and soy.
